PICS: Justin Bieber serenades Hailey Baldwin while busking in front of Buckingham Palace

Cape Town – He started out busking on the streets of Canada, and now Justin Bieber is at it again.

The Baby hitmaker was photographed and filmed busking outside Buckingham Palace in London on Tuesday.

But entertaining a crowd wasn’t the only thing on Justin’s mind. In another romantic display of affection, the 24-year-old serenaded his reported wife, Hailey Baldwin, too.

A video posted on Twitter shows the Biebs playing the guitar and telling the crowd: “That girl right there is the love of my life, right there.”
